Luke uniquely indicated that this blind beggar heard (ἀκούσας) a crowd going by or passing through (δὲ ὄχλου διαπορευομένου). He then inquired (ἐπυνθάνετο) what was going on (τί εἴη τοῦτο)? Luke was the only one to have this beggar ask a question. Matthew, chapter 20:30, has something similar, two blind men, instead of one, were sitting by the roadside (καὶ ἰδοὺ δύο τυφλοὶ καθήμενοι παρὰ τὴν ὁδόν), but they did not ask any questions as Jesus and the crowd went by them. What do you do when you hear a noisy crowd?
